LOS ANGELES — Time Warner Cable says it is investigating a blackout on its analog Fox channel in Southern California that cut off the Super Bowl for its customers. Hundreds of football fans are taking to Twitter to complain about the blackout, which occurred shortly before the halftime show. Some customers were tweeting that their service was restored shortly before 6 p.m.

Shortly after 6 p.m. Time Warner Cable officials announced the problem had been fixed.

“We have resolved a technical issue with the SD signal and apologize for the inconvenience to our customers,” Time Warner Cable spokesman Dennis Johnson said in an email.
